针对建筑施工过程的复杂性和建筑产品的特殊性,分析了影响建设项目质量的4M1E因素,结合某灰土挤密桩工程项目施工质量控制的实践,系统地分析了工程项目施工质量控制4M1E要素,从质量计划的建立、过程质量控制方面提出了相应的改善措施,旨在强化建筑工程项目全过程的动态质量控制,对提高建筑施工企业质量管理效率有一定的指导意义。 According to the complexity of building construction process and the particularity of building products, 4M1E factors influencing the quality of construction projects are analyzed. Combined with the construction quality control practice of a lime-soil compaction pile project, 4M1E elements of construction project quality control are systematically analyzed. From the establishment of quality plan and the quality control of the process, some corresponding improvement measures are put forward to improve the dynamic quality control in the whole process of construction project, which is of guiding significance to improve the quality management efficiency of construction enterprises.
